Evaluating Information on the Web

The Internet has made vast amounts of immunization resources available to parents. Unfortunately, it is sometimes difficult to determine whether the information presented is credible or not. To make an informed decision on the accuracy of immunization information on the Internet, ask yourself the following questions:

Who is providing this information?

The source of the information (i.e., organization or individual) should be made clear, and more information about the source should be available, such as what their mission is, or who they represent. Be cautious of information attributed to unnamed sources.

Is the information based on sound research?

Scientific studies published in medical journals are reviewed by qualified professionals and are therefore credible sources. Information should contain references from and to peer-reviewed publications.

Is the information up-to-date?

Reliable sites show when they were last updated. Make sure the pages have been updated recently, and that the research cited is new.

Does the information make sense?

If you find information that is too good (or bad) to be true, it probably is.

Can I find out more?

You should be able to follow up on the information through posted contact information. Additional reading lists should contain information from sources not directly linked to the site's owner.

The AAP Immunization Web site was assessed by the World Health Organization (WHO) and passed their credibility and good information criteria. It is included in the WHO's list of vaccine safety websites.(Exit site)
